I'm not sure I understood your plan. Do you intend to change the ROUTE
hook firing to happen after NEW? And since module-stream-restore would
in this case interfere with modules that do priority list routing, you'd
disable the routing part of module-stream-restore by default? I guess
that could work.
What's the default routing module going to be, if the routing part of
module-stream-restore gets disabled? Do you plan to write something from
What about other modules that affect routing in the NEW hook? Do they
pose a similar problem as module-stream-restore? If so, are they going
to be disabled also by default? If so, what's going to replace them?
